The proposed numerical procedure of determination of the stress state for axial loaded members allows implementation of the plastic and viscous behaviour of the member, whereby the problem is rendered somewhat more complex than in the case of the material having elastic properties, which was treated in this paper. Meri Cvetkovska. This can be achieved by selecting of sheets with greater thickness or depth. Coordinate system can be placed in the middle of the member, so that deflection of the middle of the member, is actually deflection of the end of the member that occurs because of external loading. Increase of the purlin distance requires increase of strength and stiffness of the sheet metal.
